Analysis and control of a unified power flow controller system

The Unified Power Flow Controller (UPFC)modeled in the synchronous reference frame is investigated in this thesis for the control of power flow in a transmission system. An AC voltage vector generated by a GTO-based inverter is injected in series with the phase voltage in the transmission line to co...
